Motorcycle ACC Deceleration Alerts for Rider Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adaptive cruise operation systems for motorcycles face challenges in deceleration, as they often result in uncomfortable experiences for riders due to the difficulty in changing lanes and the distribution of braking forces, which can lead to unpleasant deceleration magnitudes.
Innovation Solution
A driver-assistance system for motorcycles that includes a controller and notification device, which acquires information on automatic deceleration and notifies the rider when deceleration exceeds comfort thresholds, allowing for smoother adaptive cruise operations by adjusting braking forces and informing the rider to prepare for potential discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If adaptive cruise operation is implemented in motorcycles, then automatic deceleration capability is improved, but rider comfort deteriorates due to difficult lane changing and braking force distribution
Solution Approach 1:
The notification device provides advance warning to the rider before automatic deceleration occurs, allowing the rider to mentally prepare for the upcoming deceleration event. This preliminary notification reduces the shock and discomfort caused by sudden deceleration, while maintaining the automated deceleration control function.
2Productivity
If deceleration magnitude is increased to improve stopping performance, then productivity is improved, but rider comfort worsens due to uncomfortable deceleration forces
Solution Approach 1:
The system continuously monitors deceleration magnitude and provides feedback to the rider through the notification device when deceleration exceeds comfortable thresholds. This feedback mechanism allows the system to maintain effective stopping performance while keeping the rider informed and prepared for high-magnitude deceleration events.
3Reliability
If lane changing is restricted during automatic deceleration to improve safety, then reliability is improved, but adaptability worsens due to inability to change travel direction
Solution Approach 1:
The notification device alerts the rider in advance of automatic deceleration events, allowing the rider to proactively manage travel direction changes if needed. This preliminary warning enables the rider to plan alternative actions (such as manual intervention for lane changes) before the automated deceleration begins, maintaining both safety and adaptability.

AI summary
The present invention obtains a controller and a control method capable of appropriately assisting with an operation by a rider. The present invention also obtains a driver-assistance system including such a controller. A controller (60) for a driver-assistance system (10) used for a motorcycle includes: a relevant information acquisition section (65) that acquires information relevant to automatic deceleration generated during adaptive cruise operation; and a notification control section (66) that makes a notification device (70) execute notification operation to the rider in the case where the information relevant to the automatic deceleration, which is acquired by the relevant information acquisition section (65), satisfies a determination criteria.
